Tensile deformation of polytetrafluoroethylene hollow fiber membranes used for water purification
The tensile deformation behavior of polytetrafluoroethylene (PTFE) hollow fiber membranes is studied. PTFE membranes at present have sub-micron pores with an open cell structure, which plays a critical role in water purification. One of the main challenges in water purification is that the pore structure becomes covered with biofouling, leading to blocked pores. To maintain the capacity for ...

Physical methods in wastewater treatment
Physical methods of wastewater treatment are useful in water purification and recycling. We have proposed the role of nanoparticle in combination with ultrasound. Ultrasound (US), nanoparticle (NP) or in combination (US + NP) may offer an attractive proposition in the area of water purification. Ultrasound irradiation applications is that acoustic cavitation can affect a number of mechanical, ...

Everything You Need to Know About UV Water Purification
If you draw water from a well or lake and are concerned about its quality, a UV Water purification system might give you the peace of mind your water is safe to use. Households on municipal water systems are not completely safe either, as water main breaks and broken pipes which can lead to water contamination occur frequently. The ultraviolet water purification process uses ultraviolet light or ...

Verification of automatic coagulant dosage control technology based on aluminum concentration at a water purification plant
An automatic coagulant dosage control technology for water purification plants was developed to deal with rapid changes of feed water quality. Control logic was developed to decide coagulant dosage based on aluminum concentration in the mixing tanks. A coagulant-sedimentation process apparatus was installed in December 2010 in a water purification plant, and the coagulant dosage control test ...

Water decontamination by silver and copper montmorillonite
Several bactericide inorganic materials have been used for the purification of water with varying success. The characterisation of the incorporation of Ag or Cu cations in montmorillonite (MMT) clay, to obtain a bactericide material against E. coli, indicated that both outer and interlayer surfaces act as adsorption sites of AgO and Ag2O or CuO, respectively. The Ag–exchanged clays retain their ...

Synthesis of titania particles with high photocatalytic activity by high–temperature hydrolysis of TTIP in gas phase
Recently, the photocatalytic activity of titania has attracted considerable attention for solving various environmental problems. Photocatalysis is considered to be effective in air purification, water purification, and used for dealing with various types of environmental pollution. The smaller the particle size of titania, the faster the photocatalysis proceeds. Since our previous study revealed ...

What Are Some Benefits of Water Purification in Industrial Applications?
The history of water purification spans thousands of years. Water purification systems are even depicted in hieroglyphs from Ancient Egypt. Although some of these systems were primitive, such as boiling water, or filtering through sand and gravel, the goals were the same then as they are now: clean, contaminant-free water for our daily ...

Advanced technology for water purification by heterogeneous photocatalysis
The TiO2 photocatalytic degradation of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) was examined using a prototype photoreactor fabricated by Nulite. The degradation of both pollutants proved very efficient as in 12 min it was possible to bring the concentration of 2,4-DCP from 10 to 0.5 p.p.m. and in a separate experiment the concentration of PCP from 100 to 0.5 p.p.b. The effect of ...
